IPC: G02F1/1337
Filed: 1982-09-07
Abstract: PURPOSE:To obtain a liquid crystal orienting film which eliminates uneven orientation and has good moisture resistance in the formation of the liquid crystal orienting film for a nematic type liquid crystal display device, by using an aq. soln. of a specific org. titanium compd. and PVA and forming the film on the substrate by a dipping method. CONSTITUTION:Orienting films 4 are provided on the surfaces of two sheets of substrates 2 having electrodes 1 of desired shapes in contact with a nematic liquid crystal in order to maintain liquid crystal molecules 3 in parallel with the substrates 2 in a liquid crystal device wherein said substrates 2 are supported in parallel at 5-20mum spacing and the liquid crystal is sandwiched between the same. The orienting films are formed by adding Ti(OR)4 (OR is either of a hydroxy group and an alkoxy group) in an aq. PVA soln. at 0.5<=Ti(OR)4<=2 ratio to prepare a coating liquid. The substrates 2 are dipped in the coating liquid kept at 40-80 deg.C and are pulled up to form the films 4. The films are then kept at 140-250 deg.C and are thus cross-linked by heating. Then the liquid crystal orienting films which eliminate uneven orientation and have excellent heat resistance are formed with good productivity.

Title: Input circuit
Inventor: MATSUE SHUICHI
IPC: H03K5/08
Filed: 1992-05-26
Abstract: PURPOSE:To transmit signals at a high speed by setting a threshold value of an input circuit at a lower level when an input signal is kept at an L level and at a higher level when the input signal is kept at an H level respectively. CONSTITUTION:The input signal of an L level is inputted to an input signal line 1 and inverted by a CMOS inverter circuit 8. This inverted signal is outputted to an input node 3 of an inverter circuit 4 of an output part as a signal of an H level. The signal of the node 3 is inverted again by the circuit 4 and appears on an output signal line 5 as a signal of an L level which has the same phase as the input signal. Meanwhile, a threshold value control signal line 7 is fixed at an H level since a PMOSFET 6a of an inverter circuit 6 used for control of the threshold value conducts. On the other hand, the line 7 is fixed at an L level owing to the conduction of an NMOSFET 6b of the circuit 6 when an input signal of an H level is impressed to the signal line 1 respectively.

Title: Memory timing checking system
Inventor: KIKUCHI MIYOSHI
IPC: G11C7/00
Filed: 1983-08-29
Abstract: PURPOSE:To detect a memory timing error of a control signal for each nibble mode cycle by counting up a counter in response to a read or write cycle and checking the memory timing when the read or write cycle is over. CONSTITUTION:For a memory operated by a nibble mode, a counter 3 is initialized by a column address strobe signal RAS in a read cycle mode and then counted up by +1 by a row address strobe signal CAS respectively. In a write cycle mode the counter 3 is initialized by the signal RAS and then counted up by +1 by the signal which obtained an AND between the signal CAS and a write enable signal WE. Thus the contents of the counter 3 are checked at the end of each cycle to know the presence or absence of the output of a check-out signal CHOUT given from a NAND circuit 10. As a result, a normal end or an abnormal end is known. In other words, a timing error of a control signal can be detected every nibble mode cycle.

Title: X-ray content inspection apparatus
Inventor: SHIBUYA KAZUHIKO
IPC: G01F22/00
Filed: 1996-05-30
Abstract: PROBLEM TO BE SOLVED: To enable proper inspection following a change in the speed of a conveyor by changing X-ray irradiation timing so as to follow the change in the speed of the conveyor and always irradiating a container to be inspected with X-rays in the vicinity of the central position in the feed direction of the container. SOLUTION: When the speed of a conveyor feeding a hermetically closed container 10 being a container to be inspected changes, this change is applied to a main control circuit 30 through a conveyor speed detector 14 to control the respective parts of the apparatus. For example, when the speed of the conveyor increases, the conveyor speed detection pulses 15 from the speed detector 14 become short in cycle and the timing outputting an X-ray generating signal 23 is made rapid so as to follow this to control X-rays 12 so as to emit them in the vicinity of the central position in the feed direction of the container 10. The speed detection pulses 15 are also applied to a rejection timing circuit and, when a rejection start signal is received by the circuit, a rejection signal 28 is outputted to reject the container 10 from the conveyor without generating a timing error. By this constitution, even if the speed of the conveyor is changed, the container can always be inspected normally.

The output 42 of the oscillator 4 is inputted to the other input of the gate 3. The output 31 of the gate 3 becomes a pulse train, from which the pulses are eliminated during the specific period, thereby firing a triac 7 through a triac trigger amplifier 5 and a triac trigger transformer 6.

Abstract: PURPOSE: To prevent the rumple on a paper at core section, by calculating an approximate value of the hardness of winder continuously in the operation, then comparing with referential hardness to correct the set level of tension.  
     CONSTITUTION: The output from pulse oscillator 10 is counted by counter 31. Assuming the diameter of rear drum is R, number of pulse per one rotation of pulse oscillator 10 is P, winding length l=πNR/P is calculated from the output N of counter 31 through digital operator. Then winding diameter ϕ is detected by detector 15 while the diameter r of core roll is set by setter 34. Real paper depth of winding roll σ'=π(ϕ 2 -r 2 )/4l is produced from divider 39. σ' is further divided by set value σ of paper depth setter 40 to produce the ratio σ/σ'. The hardness of winding is indicated by whether said ratio is higher or lower than 1.
